SPECIFICATION forming part of Letters Patent No. 396,365, dated January 15, 1889.

Application filed July 21, l887. Serial No. 244.868. (N model.)

To all whom it may concern:

Beitknown that we, WILLIAM 0. PAUL and OSCAR D. KLEINSTEUBER, of Milwaukee, in the county of Milwaukee, and in the State of Visconsin, have invented certain new and useful Improvements in Devices for Operating Railway-Signals by Electricity; and we do hereby declare that the following is afull,

clear, and exact description thercof.

Our invention relates to signals for railroad-switches and means for operating them by electricity, and will be fully described hereinafter.

In the drawings, Figure l is a vertical longitudinal section of the mechanical portion of our invention. Fig. 2 is a vertical transverse section of the same with the magnets removed and the upper portion of the tower broken away; Fig. 3, a front view; Fig. 4, a

plan view with the tower in horizontal section, Fig. 5, a section on line 5 5 of Fig. 1. Fig. (i is a diagram; Fig. 7, an elevation of an annunciator-box forming part of our invention; and Fig. 8 is a detail. Fig. 9 is a vertical sectional view through a signal-tower of somewhat modified construct-ion, and Fig. 10 is a section on the line'lO 10 of Fig. 9.

A is the signaltower, and B is the casing that contains the mechanism for raising the 0 signals.

C is a bell-crank lever that is pivoted in the upper portion of the casing. One arm, 0, of the lever C extends downward and is connected by a link,D, with the curved short arm of a lever, D, that is pivoted to the upper front corner of the casing B, and the long arm of this last-named lever carries a daysignal, E,as shown in Fig. l. The other arm, C of lever (1 extends through a slot, a, into 40 tower A, where it is jointed by a slot and pin to the standard F of the upright signal-cage F, which latter is arranged to slide up and down in the lamp-frame c, which is provided with the usual. lenses, (2. The lamp (not shown) is carried by a cup, (I, that in turn is supported by the rods 1). The cage F is litted with the usual colored glasses, F, that are used for signaling at night.

K is a weight that is suspended in the tower A by a rope or chain, K, one end of which is attached to the tower at m, while the other, passing over a pulley, m, is Wound about a drum, L, at one end of which is a cog-wheel, L. The cog-wheel L is loose upon the shaft of the drum, but carries a pawl, N, that is held down upon the teeth of a ratchet, N, on shaft 0, by a spring, N and this ratchet is keyed to the shaft 0. The cog-wheel L is geared to the shaft H of another cog-wheel, P, by a pinion, p, and this to the shaft (1 of another cog-wheel, g, by a pinion, g and the shaft q of cog-wheel q to a pinion, R, on the shaft R of a wristwheel, R The shaft q carries a cam-wheel, S, that has an abrupt shoulder, S, that faces to the left, and the shaft R carries another cam-wheel, T, having an abrupt shoulder, T, that faces to the right.

U is a lever that is pivoted at one end to a stand, a, that is in turn bolted to the casing, while its other end, which is shouldered at .o, rests on the cam-wheel S.

wires W through battery Q and a similar signal-stand and casing, A, at the opposite approach to the switch Y of a railroad-track, and

thence by wire to a contact-piece, X, on the switch-stand .2, while wire W connects its binding-post to a contact-point, X, on theswitch-stand.

The wrist-wheel R is wristed to one end of a metal strap, '7", the other end of which is pivoted to the arm 0 of lever C, as shown in 8 5 dotted lines, Fig. 1, and full lines, Fig. 2.

The operation of my. device is as follows: The switch-lever z is formed with an insulated metallic projection, 2, which, when the switch is open, will make connection between the 0 contact-pieces X X and establish a current through the wires W W W and the electromagnets \V \V of the signal-stands, thus energizing the magnets in each stand, when the magnets will lift lever U and release camwheel S. The weight will now set the gearlng in motion, and the wrist-wheel R will draw on the strap 4 and arm C of lever C, and arm 0, drawing on strap D, will tip lever D and throw the day-signal out of the casing,

while at the same time the arm C will lift the night-signal frame F, so as to inclose the lamp by the colored glasses F This is done by a half-revolution of wheel R for as the latter completes a half-revolution the notch T of cam T will engage the upper portion of the head a; of the armature U and stop the machinery until theswitch Y is closed, when the breaking of the circuit thereby will demagnetize the electro-m agn ets \V and permit a spring, U, to draw the head 11 of armature U out of engagement with notch T, and thus again release the gearing, which again making a half-revolution will return the signals to the position shown in full lines, Fig. 1, with the head 1* of the armature in engagement with the notch S of cam S, in which position the parts will remain until circuit-is again closed by the opening of the switch.

It is obvious that the gearing may be released to expose the signals by a broken circuit by simply changing the relation. of the notches in the cams S and T to each other and changing the position of contact-points X X accordingly.

In order to apprise the switch-tender of the position of the switch or signal, we place an annunciator-box, 7a, in the circuit between one of the signal-stands and battery Q, the interior of which box is shown in Fig. 7, wherein h is an electro-magnet, 7L2 its armature, which is pivoted to the magnet-frame ii, and has a pendent arm, 1'', which is connected by a link, J with the short arm of a lever, j, that is pivoted near the lower end of the box, and to the long arm of this lever is attached a plate bearing the words open closed. The lever j is suitably guided at the top, and the armature 7L2 carries on its upper end the stem of a clapper, j, that strikes a bell, j when said armature closes 011 the magnets.

J 3 is a regulator for the armature, and J a regulator for the lever j. The electric switch G is for breaking circuit and raising the signals independently of the railway-switch.

If the signals are raised bya closed circuit, as shown in the drawings, the word open will precede the word closed if by an open circuit the word close( will be placed first.

It is evident that without departing from the spirit of our invention the glasses may be lifted above the lamp to expose it, and drawn down over the lamp to inclose it, as shown in detail in Figs. 9 and 10, wherein the signalcage F is extended by standards F so that normally (or when the magnets are de-energized) the signal-glasses F will inclose the lamp, and then when the magnets are energized said glasses F will be lifted above the flame of the lamp, as in Fig. 0, the operation being just the reverse of that of the device shown in Fig. 1.

Having thus fully described our invention, what we claim as new, and desire to secure by Letters Patent, is-

1. The combination, with a day and night signal and suitable gearing, of two cam-wheels facing in opposite directions and arranged one above the other, an. electro-magnet, and an armature-pawl, one end of which is pivoted to the casing and the other having a head adapted to engage alternately with the notches of the respective cam-wheels, awristwheel carried by the shaft of one of the camwheels, a link wristed to said wrist-wheel, and a bell-crank lever connected by said link with the wrist-wheel and toggled to the day and night signals, substantially as described.

2. The combination, with the electro-magnet and its pivoted armature having a double catch-head on its free end, of two oppositelyfaced cam-wheels, and clock-work gearing for driving them, a wrist-wheel carried by the shaft of one of the-cam-wheels, and levers linked to said wrist-wheel and to the signals, substantially as described.

In testimony that we claim the foregoing we have hereunto set our hands, at Milwaukee, in the county of Milwaukee and State of VVisconsin, in the presence of two witnesses.
